[目的]为提高蔗糖分,提前糖能型甘蔗品种开榨时间。[方法]应用甘蔗增糖增产剂对桂糖22号、桂糖26号和桂引5等糖能型甘蔗品种在未成熟前进行叶片喷雾处理。[结果]甘蔗增糖增产剂对甘蔗生长有一定的影响,品种不同影响不同,但对有效茎数、宿根蔗发株影响较小。喷施增糖增产剂后,甘蔗仍具有较大的生长量,有较好的增糖效果。同时,各品种处理都不同程度地降低了叶片中酸性转化酶活性,提高了中性转化酶活性。[结论]应用甘蔗增糖增产剂,可以提高糖能型甘蔗品种单位面积产糖量,在生产上是可行的。
[Objective] In order to improve the sucrose content, the sugarcane varieties in advance were pressed for open time. [Method] Sugar cane sugarcane varieties such as Gui Gui 22, Gui Gui 26 and Gui Yin 5 were sprayed before immature by using sugar cane yield increasing agent. [Result] The sugarcane increased production of sugarcane had some effects on the growth of sugarcane, but the effects of different varieties were different, but had little effect on the number of effective stems and sugarcane plants. Spraying sugar increase yield agent, sugar cane still has a larger growth, better sugar gain. At the same time, the treatment of all varieties reduced the activity of acid invertase in leaves to a certain extent and increased the activity of neutral invertase. [Conclusion] The application of sugar cane yield increasing agent could increase the sugar yield per unit area of sugar cane varieties, which is feasible in production.
